How does this skill help prevent reentrancy attacks?

It provides implementation guides for the Checks-Effects-Interactions (CEI) pattern and demonstrates how to correctly integrate OpenZeppelin's ReentrancyGuard to prevent recursive call exploits.

Can I use this for gas optimization?

Yes, the skill includes specialized patterns for storage variable packing, using calldata for read-only arguments, and choosing optimal data types to minimize EVM execution costs.

Is this a substitute for a professional smart contract audit?

While it significantly improves code quality and catches common bugs, it should be used as a tool for internal review and preparation for a formal audit by a security firm.

Does it support modern Solidity versions?

The skill is updated for Solidity 0.8+ which includes built-in overflow/underflow checks, but it also provides SafeMath patterns for developers working on legacy contracts.
